The Cronartiaceae are a family of rust fungi in the order Uredinales.

They are heteroecious rusts with two alternating hosts, typically a pine and a flowering plant, and up to five spore stages. Many of the species are plant diseases of major economic importance, causing significant damage and (in some cases) heavy mortality in conifers.
